The wide biodiversity and economic importance of digeneans have motivated a great deal of
research in the last decade, focussing on their phylogenetic positions. Molecular research …

This paper describes the ultrastructure of the mature spermatozoon of Heterolebes
maculosus. It is the first study of this kind concerning the Opistholebetidae (Platyhelminthes …

We describe here the ultrastructure of spermiogenesis and the mature spermatozoon of
Fasciola hepatica (Trematoda, Digenea, Fasciolidae) by means of scanning (SEM) and …

The ultrastructure of the mature spermatozoon of Gyliauchen sp., a parasite of the dusky
rabbitfish Siganus fuscescens, was studied by transmission electron microscopy. The …

This work describes the first ultrastructural results on spermiogenesis and on the mature
spermatozoon of Dicrocoelium hospes (Trematoda, Digenea) collected in Bos indicus from …

In this paper, we describe the ultrastructural organisation of the spermatozoon of a Digenea
Baccigerinae Pronoprymna ventricosa. This spermatozoon possesses the elements found in …

The mature spermatozoon of Aponurus laguncula, a parasite of the unicorn leatherjacket
Aluterus monoceros, was studied by transmission electron microscopy. The spermatozoon …

Spermiogenesis in Helicometra fasciata is characterized by an unusual flagellar rotation.
Indeed, a rotation of the axonemes, higher than 90, occurs. Nevertheless, the general …

The present paper describes the spermiogenesis and the ultrastructure of the spermatozoon
of Fasciola gigantica, as revealed by transmission electron microscopy. Spermiogenesis in …

The present paper describes the characteristic ultrastructural features of spermiogenesis
and the spermatozoon of Monorchis parvus (Trematoda, Digenea, Monorchiidae). This …
